Waveshare 34252 CM5 Gigabit/2.5G Dual Ethernet Multi-Function Expansion Board Supports RS485 Industrial Communication, 4G / 5G Module And 4K Display Output EU Plug

1. The entire casing is made of aluminum alloy, which can conduct and dissipate heat over a large area. Coupled with heat dissipation fins, the heat dissipation is more efficient
2. The detailed hole layout ensures that each interface can fit tightly to the motherboard, and the interface areas are marked with clear silk-screening for easy viewing
3. There are more abundant interfaces, equipped with ETH / MIPI / HDMI / Micro SD / USB / M.2 B KEY / M KEY and other various interfaces. They are more convenient to use
4. It supports rail brackets. The back of the host is reserved for installation screw holes, allowing it to be fixed on the rail
5. It is equipped with a standard CM5 connector, supporting the connection of Compute Module 5 Lite / eMMC series core boards
